Regarding the relations of the ureter, which is incorrect
p280 Lasts, p313NM
a.
cross the vas deferens in males
F – crossed by the vas deferns
b.
medial to the transverse processes of lumbar spine
T
c.
cross the genitofemoral nerve
T
d.
cross the SI joint
T
e.
narrowest at the PUJ
?T - Narrow at PUJ, VUJ and where they cross the SIJ into the pelvis
Summary: 25cm long, Pass inferiorly on Psoas Major under the peritoneum,
crosses in front of the genitofemoral nerve, the gonadal vessels cross in front of
the ureter, it leaves the psoas at the bifurcation of the common iliac, goes over
the SI joint and enters the pelvis, the vas def goes over it
X-ray: Medial to the tips of the TV processes of the lumbar vertebrae and
crosses the pelvic brim at the SIJ
23.
The ureters. Lasts p280
a.
The PUJ is the widest diameter
T - (saunders agrees)
b.
Are dependant on innervation from the renal pelvis
for peristalsis
F - they have intrinsic pacemaker ability
c.
Lie lateral to the transverse processes of the lumbar
vertebrae
F - just medial
24.
Regarding the urethra
a.
Is 20cm long
T - In males yes, females a measly 4cm lasts p312
b.
Does a right angle bend in spongy part of urethra
F - Mine doesn’t....There is a 90 degree turn from the spongy to the
membranous
c.
Narrowest point is at prostate
F - ext meatus
d.
Narrowest point is at navicular fossa
F - ext meatus
e.
Runs in corpus carvernosum
F - spongiusum
25.
Regarding the testicle p228 NM, p222Lasts
a.
It has no parasympathetic supply
T - Can’t find it in books but Blitz reckons it has vagal supply. Best answer.
b.
Appendix is inferior
F - Do they mean epididymus which is posterolateral
c.
Vas deferens in somewhere
F
d.
Epididymus is somewhere else
F
e.
Drains to paraaortic and inguinal nodes
F - paraaortic only
f.
The pampiniform plexus is a superficial venous plexus
surrounding the testicular artery
T - p228 NM best answer (Blitz, adam, saunders agree)
g.
The testicular artery has numerous anastomoses with
the cremasteric artery
T - It anastomoses with artery to vas def AND cremasteric artery
(but they are not sufficient to maintain supply to the testes
(Saunders don’t agree)
h.
Division of the testicular artery results in testicular infarction F - No will cause atrophy, not infarction
26.
The duodenum
a.
is a retro-peritoneal structure
F - Partially only: the 4
th
isn’t
b.
is 25cm in length
T
c.
lies between the levels of L2-L4
F - L1-L3
d.
in it’s 4
th
part lies to the right of the aorta
F - to the L
27.
Which of the following the appendix is UNTRUE
a.
it has a base constant in relation to the caecum
T
b.
it has it’s own mesentery
T
c.
it is formed by teneae coli convergence
T - ?
d.
varies in length between 2 and 25 cm
T - Apparently can be
e.
it always lies retro-ileal in prescence of disease
F
28.
The ureters p280 Lasts
a.
widest in diameter at the PUJ
T - (saunders)
b.
innervated by sympathetic nerves T12-L1
F - T10-11 (accord to Moore it would be TRUE: t11-L2...
c.
lie lateral to the tips of the lumbar transverse processes
F - just medial
d.
depend on innervation from the pelvis for peristalsis
F - have independent pacemakers
